DALI Input Devices — Part III: Occupancy Sensors
How a DALI occupancy sensor builds the occupied state, why the command that cancels the hold timer sometimes does nothing, and when to move the hold time into the application controller.

DALI Input Devices — Part II: Light Sensors
How a DALI light sensor generates events, the two schools of daylight harvesting configuration, and why the same number from two sensors describes completely different light levels.
DALI Input Devices — Part I: Push Buttons
How push buttons generate events on the DALI bus, why the same long press is handled two different ways by application controllers, and where the configuration faults that never report an error come from.
Nine Common DALI Bus Faults and How to Diagnose Them
Nine typical DALI bus faults — mechanism, how to spot each one and how to fix it: from missing voltage, short circuits and wrong connections to mains or PE, through luminaires feeding the bus and devices that light up but never answer, to addressing and bus flooding.
